Answer:
One chance in two
Explanation:
A parent can only have one or the other meaning a son or daughter. Both the son and the daughter represent one half of a probability of having each one separately. On whether or not the parent will have a daughter as the eighth child, is completely irrelevant as a parent can only bare a son and daughter. This would mean they would have a one chance in two for either cases, but due to the context of the question, it would be for the daughter. So therefore, they would have one chance in two.
Thank you,

The graph predicts the effect that each factor would have on the biodiversity of the mediterranean sea in the next 10 years. however, if the government introduces laws prohibiting hunting, it would somewhat reduce the impact (eutrophication, exploitation, pollution) would have on the biodiversity. similarly, if laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect (exploitation, climate change, invasive species)would have on the seas biodiversity.
<h3>
What is eutrophication?</h3>
In an aged aquatic habitat like a lake, eutrophication is the progressive rise in the concentration of phosphorus, nitrogen, and other plant nutrients.
Because hunting is primarily done for amusement or to obtain treasures from animals such skin, horn, ivory, and venome for selling on the global market and reaping enormous profits from them, hunting would have a somewhat smaller influence on biodiversity if the government passed laws outlawing it. The introduction of a hunting ban will lessen the killing and use of animals as commodities.
The impact that invasive species would have on the waters would be reduced if regulations limiting the entrance of new plant or animal species within the nation were implemented. Living things that invade or migrate to new areas in quest of resources are known as invasive species. Native species suffer due to competition from these species, which causes a fall in native species. As a result of the fall in native marine species and potential extinction of native species, this will affect the actual biodiversity of the ocean.

Answer:
The possible blood types their children could have are A or 0.
Explanation:
The I gene determines the blood type of a person. I is the dominant allele, while i is the recessive allele.
- IA dominant over i. The person presents A type of antigens.
- IB dominant over i. The person presents B type of antigens.
- IA and IB are codominant. The person presents both types of antigens, A and B.
- i is the recessive allele. The person does not present any antigen.
Cross: a person who is blood type O with a person who is blood type A
Parental) ii x IA-
Gametes) i i IA -
Punnet Square) IA -
i IAi -i
i IAi -i
The - symbol represents the possibility of either IA allele or i allele. This is, the parental with blood type A might have the genotype IAIA or IAi
F1) 2/4 = 1/2 IAi
2/4 = 1/2 -i (-i could be either IAi or ii, depending on the genotype of the parental with blood type A)
- <u>Option 1</u>: ii x IAIA
F1) 100% IAi (The whole progeny will have blood type A)
- <u>Option 2</u>: ii x IAi
F1) 50% IAi (Half of the progeny will have blood type A)
50% ii (Halfa of the progeny will have blood type 0)
The possible blood types their children could have are A or 0.

When the first act is finished should be the answer.
Answer:
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. Crystallization, erosion, sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another. The process by which a rock changes form or mineral content as a result of environmental changes such as heat and pressure. a rock that was altered by metamorphism.
